Rolling device

Abstract

Rolling device comprising a housing ( 11 ) accommodating a rolling element and a control and communication module comprising a wireless receiver ( 30 ) connected to a control device ( 40 ) and position means ( 50 ) connected to the control device, wherein the rolling device further comprises driving means ( 60 ) connected to the control device and the rolling element for driving and controlling the movements of the rolling element according to a first position acquired by the position means and a received wireless signal comprising movement instructions and a second position, power supply means ( 70 ) for powering the control and communication module and the driving means, wherein the housing is arranged with an support assembly for bearing the rolling element which is configured for establishing a releasable connection with the housing, and an electrical interface adapted for establishing connection between the rolling element and the control and communication module and the power supply means.

The invention claimed is: 
     
       1. A rolling device for a device to enable moving the device along a surface wherein the rolling device comprises:
 a housing arranged for attachment to the device and arranged for accommodation of a rolling element, wherein the housing is arranged for accommodation of a control and communication module comprising;
 a wireless receiver connected to a control device 
 position means connected to the control device for acquiring the position of rolling device relative to its surroundings, 
 
 driving means connected to the control device and the rolling element for driving and controlling the movements of the rolling element according to the first position acquired by the position means, and a received wireless signal comprising movement instructions and the second position, 
 power supply means for powering the control and communication module and the driving means, wherein 
 the housing is arranged with
 a support assembly for bearing the rolling element and is configured for establishing a releasable connection with the housing, 
 an electrical interface adapted for establishing connection between the rolling element and at least one the control and communication module and the power supply means. 
 
 
     
     
       2. A rolling device in accordance with  claim 1 , wherein
 the rolling element comprises a wheel element arranged with a wheel axle, 
 the support assembly comprises a first and a second wheel bearing member each connected to an end portion of the wheel axle, 
 the first wheel bearing member is releasably arranged in a first guiding recess arranged in the interior of the housing, 
 the second wheel bearing member is releasably arranged in a second guiding recess arranged in the interior of the housing, wherein 
 
       the first wheel bearing member and the second wheel bearing member carrying the wheel element is to be released from and installed into the housing as a unit. 
     
     
       3. A rolling device in accordance with  claim 1 , wherein attachment means for establishing releasable connection between the support assembly and the housing is to be selected among the following devices; magnets, click/out connection, releasable claw connection, plug and socket connection. 
     
     
       4. A rolling device in accordance with  claim 2 , wherein
 a first guide member is arranged in the first guiding recess and is arranged for establishing releasable connection with the first wheel bearing member, 
 a second guide member is arranged in the second guiding recess and is arranged for establishing connection with the second wheel bearing member. 
 
     
     
       5. A rolling device in accordance with  claim 4 , wherein the rolling device comprises a drive motor wherein
 the first guide member and the first wheel bearing member is connected as a unit, 
 the second guide member and the second wheel bearing member is connected as a unit, 
 
       and the drive motor is arranged for displacement of the these units in their respective guide recess for moving the wheel element 
       between an extended position where the wheel element projects outside the housing and a retracted position where the rolling element is located inside housing. 
     
     
       6. A rolling device in accordance with  claim 5 , wherein the drive motor has a spindle connected to a bridge structure by a toothed intermeshing arrangement, wherein the bridge structure has a first attachment section connected to the first guide member, and a second attachment section connected to the second guide member for displacement of the wheel element between an extended and retracted position. 
     
     
       7. A rolling device in accordance with  claim 5 , wherein the drive motor is arranged with centred spindle having two free end portions wherein
 one of the end portion forms a toothed intermeshing engagement with a first attachment section connected to the first guide member, 
 the other end portion forms a toothed intermeshing engagement with a second attachment section, 
 
       for displacement of the wheel element between an extended and retracted position. 
     
     
       8. A rolling device in accordance with  claim 1 , wherein
 the electrical interface comprises a wired interface for communication to and from the roller element, and 
 
       the second guide member comprises first connector parts 
       the second wheel bearing member comprises second connector parts, wherein the first and second connector parts are arranged in a releasable connection. 
     
     
       9. A rolling device in accordance with  claim 1 , wherein the rolling element comprises the driving means. 
     
     
       10. A rolling device in accordance with  claim 1 , wherein the electrical interface comprises a wireless interface for communication to and from the rolling element.
